ABSTRACT:
A syringe is disclosed which includes a needle body having a proximal end and a distal end, a needle attached to the distal end of the needle body, a plunger for drawing fluid into the needle body through the needle, and a protective sheath configured and dimensioned to be positioned about the needle body and movable between a first distal position whereby the needle is shielded by the sheath and a proximal position whereby the needle is exposed. A system of slots and pegs is provided to releasably retain the protective sheath in the first distal position and to releasably retain the protective sheath in the proximal position. Also a system to retain and lock the protective sheath in a second distal position after use whereby the needle is protected by the sheath. A method of using the safety syringe to protect the needle from inadvertent contact with the user or any person in the area of use is also disclosed.
